BOBBIN AND SPINDLE CONNECTOR- SPECIFICATION forming part of Letters Patent No. 795,008, dare-a muy 1s, 1905.

Application filed December 23, 1904. Serial No. 238,092.

To (,LZ/l 11171/0111, 'll/z 777,04/ cm1/cern:

Be it known that we, Jo'r-IN RoNnY ,and JOHN (j. RAE, citizens of the United States, residing at Voonsocket, in the county of Providence and State of Rhode Island,have invented new and useful 'Improvements in Bobbin and Spindle Connectors, of which the following is a specification.

Our invention pertains to spinning, and more particularly to bobbin and spindle connectors; and it has for its object to provide a connector designed more especially for holding worsted-bobbins to their spindles and one which is simple and inexpensive in construction and embodies no delicate parts, such as are liable to get out of order in practice.

The invention will be fully understood from the Jfollowing description and claims, when taken in connection with the accompanying drawings, forming part of this specification, in which- Figure 1 is a View illustrating the relative arrangement of a spindle, a bobbin of the worsted type, and the connector constituting the preferred embodiment of our invention. Fig. 2 is asection taken in the plane indicated by the line 2 Q of Fig. 1 looking upwardly and showing the connector minus the cup e. Fig. 3 is a detail section taken on the line 3 3 of Fig. 1. Fig. 41 is a perspective view of one of the bobbin-engaging' members of the connector removed; and Fig. 5 is a horizontal section taken in the plane indicated by the line 5 5 of Fig. 1--11 e., immediately below the bobbin.

Similar letters designate corresponding parts in all of the views of the drawings, re-

ferring to which- A is a spindle. B is a bobbin of the worsted or any other type arranged on the spindle land having its bore enlarged at its lower end, as indicated by a in Figs. 1 and 3, and O is the connector, constituting the preferred embodiment of our invention as a whole. connector comprises a body designed to be secured on the spindle A, so as to turn therewith, swinging members c, carried by the body and arranged to rest in the enlarged bore t of the bobbin after the manner shown in Fig. 1, and a suitable spring CZ, tending to The said` move the lower arms of the members o toward each other, and thereby force the upper or clamping arms of the members outwardly against the wall of the bore or bore enlargement a of the bobbin with a view of frictionally holding the bobbin to the spindle and causing the former to rotate with the latter. The connector O is also shown as comprising` a cup c, which contains the bodyb and the parts carried thereby and has for its function to serve in connection with the body to exclude dirt, lint, Sac., from the interior of the connector. This cup, however, is not essential, and it may therefore be omitted when desired Without involving a departure from the scope of our invention. In the construction shown the body of the connector has a flat top f. designed to serve as a rest for the bobbin, a central threaded aperture designed to receive a complementary threaded portion of the spindle, whereby the body is secured to the spindle, and notches g, disposed at opposite sides of the threaded aperture and having upwardly and inwardly inclined inner end walls t, Fig. 1. The members @of the said construction respectively comprise an upper or clamping arm of concavo-convex form in cross-section, an intermediate portion Z, designed to rest in one of the notches f/ of the body and havingatlat upper side arranged to rest fiusli with that of the body and also having arounded outer end arranged to rest Hush with the perimeter of the body, and a lower arm 72, having a groove rin its outer side. The spring d, comprised in the said construction.I is of the endless coiled type, as best shown in Fig. 2,v and is designed to surround the lowerarms p of the members c, so as to tend to yieldingly press the upper or clamping arms thereof outwardly.

In assembling the parts of our improvements the cup e is placed on the spindle A against a shoulder s thereof, and after the members c are fulcrumed in the body 7) on pins t, extending transversely across the notches g, and the spring dis mounted in grooves r in the lower parts of the members c the body is screwed on the .threaded portion of the spindle until its upper side and the upper sides '/n/ of the members c rest flush with the upper edge of the cup e. With this done the connector is ready for use.

In the practical use of the improvements it will be observed that the spring Z will tend to yieldingly press the upper or clamping arms ot' the members c outwardly, and hence when the bobbin is pressed downwardly on the upper arms of the members, as shown in Fig. l, the said arms will trictionally hold the bobbin to the spindle and cause the former to turn with the latter.

It will be gathered from the foregoing that our novel connector is at once reliable in operation, is simple and compact, and is so constructed that it is well adapted to withstand for a considerable period the usage to which bobbin and spindle connectors are ordinarily subjected.

We have specifically described the construction and relative arrangement of the parts included in theH present embodiment of our invention in order to impart a definite understanding of the said embodiment. Ve do not desire, however, to be understood as coniining ourselves to the said specilic construction and relative arrangement of parts, as such changes or modifications may be made in practice as fairly fall within the scope ot' our invention as claimed.

Having described our invention, whatwe claim, and desire to secure by Letters Patent, 1s-

1. The combination of a spindle, a bobbin arranged on the spindle'and having a bore in its lower end, and a connector comprisinga cup supported on the spindle, a body secured on the spindle and having recesses and arranged in the cup with its upper side flush with the edge of the cup, and spring-actuated members mounted to swing in the recesses of the body and having intermediate portions the upper sides of which are Hush with the upper side of the body and the edge of the cup, and also having clamping-arms disposed in and exerting outward pressure against the wall of the bore in the bobbin.

2. The combination of a spindle, a bobbin arranged on the spindle and having a bore in its lower end, and aconnector comprisingacup supported on the spindle, a body secured on the spindle and arranged in the cup with its upper side iiush with the edge of the cup and having recesses disposed at opposite sides of the spindle, members pivoted in the recesses of the body and having intermediate portions the upper sides ot' which are Hush with the upper side of the body and the edge of the cup and also having upper clamping-arms disposed in the bore of the bobbin and lower arms grooved at their outer sides, anda coiled spring surrounding the lower arms of the members and contained in the cup.

3. The combination of a spindle, a bobbin arranged on the spindle and having a bore in its end, and a connector comprising a cup supported on the spindle, a body secured on the spindle and arranged in the cup with its upper side iiush with the edge thereof, and springpressed bobbin-holding members carried by the body and having portions arranged to press outwardly against the wall ot' the bore in the bobbin, and also having portions arranged ilush with the upper side of the body and serving in connection therewith to close the cup.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
